"Local schema mismatch from server" - when defining multiple rooms/states
See original GitHub issueThis error is reported often, and one of its causes is when multiple room/state classes are defined in the server with the same schema “context”.
Internally, every @type()
call is going to register the property in a “global” context:
import { type, Schema } from "@colyseus/schema";
class State1 extends Schema {
@type(...) my_prop
}
class State2 extends Schema {
@type(...) my_prop
}
To avoid registering every schema in the global context, you can create a different context like this:
import { Context, Schema } from "@colyseus/schema"; // do not import "type" here
const type = Context.create(); // this is your @type() decorator bound to a context
class State2 extends Schema {
@type(...) my_prop
}
Actions needed:
- Update documentation to encourage creating different contexts, especially in Unity because of the crash
- Throw WARNING on the client-side instead of ERROR when handshake sends more structures than necessary

Hi @sorrow31812, for plain JavaScript it is a bit complicated, the general suggestion is to always use TypeScript:
Make sure you use the specified
context
for every structure your state depends on, otherwise the “schema mismatch” is going to happenhello dear friends i have this error only in android build of unity (apk), in editor when i running game every thing is ok
